CC -!- FUNCTION: The replicase polyprotein 1ab is a multifunctional protein:
CC it contains the activities necessary for the transcription of negative
CC stranded RNA, leader RNA, subgenomic mRNAs and progeny virion RNA as
CC well as proteinases responsible for the cleavage of the polyprotein
CC into functional products.
CC -!- FUNCTION: The Nsp1 chain is essential for viral subgenomic mRNA
CC synthesis. {ECO:0000250}.
CC -!- FUNCTION: The 3C-like serine proteinase chain is responsible for the
CC majority of cleavages as it cleaves the C-terminus of the polyprotein.
CC {ECO:0000250}.
CC -!- FUNCTION: The helicase chain, which contains a zinc finger structure,
CC displays RNA and DNA duplex-unwinding activities with 5' to 3'
CC polarity. {ECO:0000250}.
CC -!- FUNCTION: [Uridylate-specific endoribonuclease nsp11]: Plays a role in
CC viral transcription/replication and prevents the simultaneous
CC activation of host cell dsRNA sensors, such as MDA5/IFIH1, OAS, and PKR
CC (By similarity). Acts by degrading the 5'-polyuridines generated during
CC replication of the poly(A) region of viral genomic and subgenomic RNAs.
CC Catalyzes a two-step reaction in which a 2'3'-cyclic phosphate (2'3'-
CC cP) is first generated by 2'-O transesterification, which is then
CC hydrolyzed to a 3'-phosphate (3'-P) (By similarity). If not degraded,
CC poly(U) RNA would hybridize with poly(A) RNA tails and activate host
CC dsRNA sensors (By similarity). {ECO:0000250|UniProtKB:P0C6X7,
CC ECO:0000250|UniProtKB:P19811}.

CC -!- ALTERNATIVE PRODUCTS:
CC Event=Ribosomal frameshifting; Named isoforms=2;
CC Name=Replicase polyprotein 1ab; Synonyms=pp1ab;
CC IsoId=Q83017-1; Sequence=Displayed;
CC Name=Replicase polyprotein 1a; Synonyms=pp1a, ORF1a polyprotein;
CC IsoId=Q83017-2; Sequence=VSP_032889;
CC -!- DOMAIN: The hydrophobic domains (HD) could mediate the membrane
CC association of the replication complex and thereby alter the
CC architecture of the host cell membrane. {ECO:0000250}.
CC -!- PTM: Specific enzymatic cleavages in vivo by its own proteases yield
CC mature proteins. There are two alternative pathways for processing.
CC Either nsp4-5 is cleaved, which represents the major pathway or the
CC nsp5-6 and nsp6-7 are processed, which represents the minor pathway.
CC The major pathway occurs when nsp2 acts as cofactor for nsp4 (By
CC similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: [Isoform Replicase polyprotein 1ab]: Produced by -1
CC ribosomal frameshifting at the 1a-1b genes boundary.
CC -!- MISCELLANEOUS: [Isoform Replicase polyprotein 1a]: Produced by
CC conventional translation. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the arteriviridae polyprotein family.
CC {ECO:0000305}.
